| Abstract: | The case of studying N-allcylation by using the inorganic supported reagent for benzotriazole was reported. The inorganicsupported reagent was composed of potassium hydroxide and sodiumhydroxide and potassium carbonate separately supported on alumina. Theorder of catalyst activity for the inorganic supported reagent was KOH/Al_2O_3>K_2CO_3/Al_2O_3>NaOH/Al_2O_3, and the catalyst activity of the inor-ganic supported reagent was increased according to concentration of basicaction. Particularly, comparing with dehydrated potassium carbonate asbinding acid agent, the catalytic action of the new supported reagentK_2CO_3/Al_2O_3 was much more powerful than dehydrated polassium carbonate,and also it could chang the way of the reaction. When suitable solventwas selected, the reaction effect of this supported reagent was good. |
